Four-storey tower built over Main Street in 1777 on the site of Trinity Castle. It was used as a prison until 1837, and rebels were hung from its windows. It's now a museum.

Founded by St Declan in 450, parts of this church go back to 1220. It became a collegiate church in 1464, meaning it didn't have a permanent priest, but the staff of the religious seminary took turns. The Catholics were ejected in the Reformation and the land passed to Sir Walter Raleigh, who sold it to Robert Boyle. Most of what's there now reflects Boyle's rebuilding in the 17th century. He was the father of Boyle the physicist and lived at Lismore castle; he's buried in the graveyard here. Part of the town wall flanks the graveyard. The church remains Church of Ireland (Anglican).
